in constructiegD the apparatus there is eniployed a. niain traine con'iprisinr a head portion o. connected to a transverse yoke' by connecting rods Supported in said iuain l'raine is an electroinagnct coi'nprising; two coils o and (il. There is also carried on the nn'iin trarne a permanentmagnet b3. Pivot4 ally connected to the head portion (t at the -point c1 is an armature c attracted by the electroinagnet coils Z1 and (il upon the closinfnr of the circuit therethrough. Carried upon ay suitable bracket projecting troni the inain traine and insulated one from the other and :troni said main fanie are four contacts ail, m2, y1 and 1.1/2 rcpresent-img1 the terminals of the two circuits or two portiens ot a single circuit to he connected hy the apparatus. connected one with the other hy an interino diate insulated connector 'ya wherebyi said contacts will he tiexed in unison. rlhe arinature c carries a. pendant linger-c2 `which in. turn supports a stud c3 of insulating material which rests upon the uppermost contact rc1. lli/hen the coils Z), o1 are energized 'oy the cloeing,1 of the circuits therethrough the armature e is attracted. by said coils o, ol

and drawn downward against the tension the {ieiiilile contact blades eil, ai?, thcrehy henclingl said contacts ml, m2, into engagen'ient with the alternating contacts .iz/1 and i/2 and closing the circuit hetween i1# and y1 and between .r2 and fi/2. ln order to inaintain the apparatue in its operated condition until released by the oijicrator-tliere is pivotally supported upon thecontrol armature c a polarized armature ai. rthe polarized armature ril is provided with a truniiion all mounted in e suitable bracket Z2 secured to the under side of the control arniaturec. rllhe outer end ot the bracket clg'is bent downward and provided with an opening dit through which the polarizedl armature Z projects; The slotted opening;` d3 in the downward progectiiig ciitrcinity of the tiret-liet Z2 liinits the oscillation or' the polarized armature in either direction. 'Pio jecting upward troni the head portion n, ot' the inain 'fr-anic is a shouldered projection c under the `shoulder er' of which the polarized ari'nature d is adapted to engage to loclt the control armature c in its operated position.

in installing the apparatus the coils t) and ZN are bridged across the main or operating The contacts rc1 and u? are circuit while the terminals of said main circuit are connected to one set of the contacts while the terminals of the other circuit io be connected with the main circuit are con'ziecoid with the second set of terminals. .lt is immaterial whether the main circuit be connected with the contacts w1 and .2:2 or willi y1 and y`. The apparatus being so connected an electric impulse is transmitted in one direction orer the line energizing the coils Zi? 71] which attract the control armatore c. rl'lie control armature c approaching the coils o, b1 lexes the contact blades el and The saine impulse causes the polarized armature 1l to be oscillated upon its trun- 'nion Il toward the coil o whereby it will be engaged. beneath the shoulder el of the projection c. Thus the armature is held in its `depressed or operatedposition after the coils o, b1 are deiinergized. lt'is seen that the oseillation el the control armature c closes the contact between the ieizible blade ai] and y1 and e and y? thereby connecting the main or operating circuit with the second circuit, and the armature is locked in its operated position by the operation ot the polarized armature d. rhis is the condition of the parts as shown in Fig. 3. `When it is desired to disconnect the circuit an impulse is transbinitted over the main line in the` opposite direction again energizing the coils o, b1 but causing the. polarized armature d to swing in the opposite direction or toward the coil l and from under the shoulder el of the projection e thereby releasing the control armature c which will be elevated by the elasticity o1 the spring contact blades m1 and m2.

lu Fig. 5 there are represented two telephone exchanges X and Y from which eX- tend subscribers lines a: and y respectively. rlhese subscribers lines and y normally independent ot each. other are adapted to be connected one with the other to forni an intci'-coifninunicating line between vthe two changes. In the present instance' the coniiection et these lines is under the control of the ope ator of exchange X. The coils b and [il are bridged across the'. subscribers line and the two sides of said siibscribei"s line 0J are connected to the contact blades a and m2. 'ihe two sides o'l'A the subscribers line y are connected to the contact blades y1 -and i. ltelerring to the exchange X? fis the .master switch adapted to bring into the circuit either the annunciator g, tie operators instrument or to connect with the subscrib ers. line the circuit from the battery z' in which .is included an impulse transmitting key and a pole changer il. rhe master switch j eing. closed with the circuit the imv pulse key j is operated to send an impulse over the subscrihers line .olksiicli .an impulse momentarily energiaes the coils b and o* which attracting the armature c serves to close lthe contacts between the contact blades a, y1 and fvg, gf thereby joiningr the two subscribers circuits and y. The saine inipiilse causes the polarized arni-.itureil to swing toward the coil Z and under the shoulder el of the projection c thereby locking the armature e in its operated position. ll'hen it is desired to release the apparatus or to disconnect the subscribers lines a: and 1/ the pole changer le shifted reversing the polarity of the circuit whereupon an im pulse transmitted over the line by again closing the key j will momentarily,T energize the coils ZJ and o1 and cause the polarized armature d to swing toward the coil ZN and (from under the shoulder el of the projet-.tion c 'thereby releasing the armature c. lt is obvious that an additional instrument may be bridged .across the line y thereby enabling the lines to be connected from .either exchange.

Frein the above description it will be apparent that there isthus produced a nia-- chine of the character described iiossessing the particular' features of advantage bel'ore enumerated. as desirable but which obyiousl y is susceptible of modification in its forni, proportion, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
